To all whom it may Concern.'

Be it known that I, CLIFTON W. SHERMAN, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Side Frames for Car- Trucks, of which the following is a specification.

In the side frames of trucks such as commonly used for freight cars it has heretofore been customary to connect the upper arch bar with the lower arch bar and tic bar by means of columns arranged on opposite sides of the spring plank and bolster and composed of pillars extending from the upper to the lower bars and vertical tie bolts which operated to connect the arch bars and tie barswith said pillar, said bolts engaging their nuts and bolts against the upper side of the u per arch bar and the underside of the tie Iliar. This construction has been found objectionable on account of the frequent breakage of the bolts and loosening of the nuts and heads thereof which permitted the central part of the arch bars and tie rods to sag or drop upon the track under the weight of the load imposed upon the same and thereby not only damage the roadway and wreck the cars but also frequently result in the loss of life.

It is the object of this invention to provide improved means for connecting the upper and lower arch bars and the tie bar or' similar longitudinal bars so as to eliminate the use of vertical tie bolts and to so construct these connecting means that the possibility of breakage of this connection is practically avoided, thereby insuring greater security in the transportation of freight and also avoiding the loss of rolling stock which has heretofore been occasioned bythe breakage of the vertical tie bolts. This desirable improvement is obtained in the present invention mainly by combining the advantages of arch bars with yoke-shaped columns constructed principally of cast steel which not only insure greater .economy but also increased safety. y

Similar characters of reference indicate corresponding parts throughout the several views. 1 y

Referring to Figs. 1 to 5, 1 represents the upper' longitudinal arch bar, 2 the lower longitudinal arch bar arranged below the upper bar, 3 the longitudinaltie bar` ar ranged below the lower arch bar,4f the journal boxes which are mounted atopposite ends of the upper and lower arch bars and tie bar, 5 the axles journaled in the journal boxes and 6 the wheels mounted on the axles.

`The inner or opposing sides of the wheelsA are engaged by the brake shoes 7 which are mounted on transverse brake beams 8. Above the central part of the lower arch bar Gti is arranged the spring plank which in the,

present construction is made in the form of a channel bar having its web 9 arranged horizontally and its flanges 10 projecting upwardly. Upon. this plank the lower ends of acluster of springs 11 are inoiiirtedpref-l erablyby means of a' wooden block 12 inter*n posed between'tliese ends of these-springs Y .partsjust described are of the usual and well vknown construction and havebeen in .common use in side frames for car trucks of 'this` character.

.In 'carrying-.out my invention` for use in car trucks having a comparatively long wheelbase, as shown in the construction repiresented in Figs. 1 and- 2, it is preferable to employ two inner upright columns 15, 15 which are arranged on opposite sides oit the spring plank and bolster and connected with the upper and lower arch Ibar and tie bar as well -as with the spring plank and serve as arguide for the bolsterf and two outer colnnins`f16, 16 which connect the upper' and lower-arch bars and the tie bar and serve as a support Jfor the brake beams.

'In the construction 'shown in Figs. Ito 5, .eachV of the inner. columns 15 comprises an .upright y yoke-shaped pillar 17 y.preferably constructed of cast steel and provided in its upper part with a vertical lslot 180 1which opens in the direction or the length of the .side .frame and ein lits lower end with a notch 85 Vor recess 80 which 4opensdownwardly and 'formsadownwardly facing seat S01 at the upperendvofthisrecess. `l v'The lower arch" bar2 is arranged in the recesses-S0 and bears 'withits upper side 40againstthe seat 801 at the upper lend of this recess and' the tie bar'is also arranged in this recess'and engages its upper side' withY u Y inents'by means of. guide lugs 660 arranged theundersideof the lower arch bar. The

lower arch bar. and tie bar are securely held against longitudinal displacement in this re- 'cess ofthe pillar 15 bya vertical locking j pin 81' projecting downwardly .from the top of thevrecess 8.() through corresponding vertical openings 82, 33 in thetie bar `and lower archfbar, andfthese last mentioned'bars are `confinedinlsaid recess and in engagement n withwsaid-locking pin`81 by a key 82 passingj'transversely and vhorizontally 'through corresponding openings inthe walls of said "re"cess sov 'as to' engage` `the underside of the l tiejbar andprovided `at Vone'end with a head '3.83 'engaging'with the outer sideotfone wall fof the recess andliaving a cotter pin 84 in "its :bther'end which'engages with the outer side oixof thebtlizer recess wall. .By this means the .ilower -arch bar and the tie barmay be readily attached lto `or detached fromV "thev pillar fiorY convenience in 'manufacture' or. 'making plank engages its vunderside Awith fthe upper side of the lower arch bar. A The.; spring l i plankmaybe held in place byganysuitable means, for instance by securing its vertical flanges 10 byr-ivets 140 `or otherwise to lugs e1-30 projecting laterally :trom the inner and ,outer sidesotthe lower parts of the inner vby various ineagnsithose shown in Figsgl vto ybeing suitable'and comprising. a locking` wear block 590 arranged iiixtheupper part oit Y the" slot 180 and provided with a locking pin 580 v preferably formed integrally therewith and projecting upwardly from Vthe up? per end thereof through an opening 210 formed in the adjacent part of' the upper arch lbar and into a recess orfsocket 220 formed in the upper seat lllofltliepillar 15. The locking block may be held in its proper place within the slot.180 o't' the .pillarl by various means. such as transverse locking pins 630 passing horizontally througli'coinciding openings in the lower part of' this locking block andthe adjacent parts ,the pillar 15 and engaging thehead 631 atfits ysa inner end against the inner 'sideof said-pillar and the opposite end of tliis .locking pin ,is provided with a Cotter.632 adjacentitoV the outersde oi? saidE pillar. A- very" simple, strong and durable connection between each inner pillar and the upper bar` is thus produced whichholclsthese parts reliably in place so that they will not give way under the heaviest strains to which-they are liable to be subjected in use.

When it is'desired to remove thebolster- 13 Athe locking pins '63()l are i'irst removedwhich Vpermits ion placed by assembling the parts-mentioned reversely to the order `just. described.

A"Iheweb ofltliefspring easily renew'edit is possible to keep the'triiclr always 'in' good-condition; y l

:terasse W Each ot the outer or end columns 16 coinprises an upright yoke-shaped pillar' 16() provided in its upper part with a Vertical slot 161 the upper end ot which forms a downwardl7 facing upper seat 182, while its lower part is provided with a recess 800 which opens downwardl7 through the lower end ot the pillar and forms a downwardl'5fv facing seat S02 at the upper end ot' said recess. rThe lower arch bar and tie are `ar ranged in the recess 800 and the upper side ot the tie bar engages with the seat. 802 while the undersioe ot the tie bar is engaged by a horizontal key 820 passing transrerseliT through corresponding openings in the walls of the recess 800 and having` a head 830 at one ot its ends bearing against the outer side of one of these walls7 and a Cotter pin SL10 in its other end bearing `against the outer side ot the other ot these walls, as shown in lfigs. 1 and e. Each of the pillars 160 is provided with a locking pin 310 projecting dormwardlr i'roin its lower seat 802 through corresponding` openinn's 330. 320 in the lower arch bar and tie bar, as shown in Figs. 1 and lla, thereby holding these part-s against longitudinal movement ii'elativcli7 to each other. The upper arch bar passes through the vertical slot ot each end pillar and is held with its upper side in engagement with the upper seat 182 by means ot a transverse keV or pin 183 preterabli7 haring the form of a wedge, shown in Fia. 4;, and passing through openings in the adjacent part of the respective end pillar and engaging' with the underside ofthe upper arch bar and haring its head 184: arranged outside of one wall of the respective pillar and a Cotter pin 185 in its other end arranged outside ot the other wall ot said pillar. lVhen the parts are assembled the wedge members 183 have their length arranged perpendicular to the. plane ot the 'traine and are driven between the upper arch bars and the adiacent portions of the integral column portions for tightenine` and connecting the same,

BV this means the columns are lirinly and reliably connected with the longitudinal upper arch bar, lower arch har and tie bar so as to torni a rigid and durable connection with the same which is not liable to gire way or become displaced under the sercro strains to which the saine are subjected while in use, thereby preventing the side traine from droppin and causing accidents such as havelreduently occurred in the past when usingvertical tie bolts for holding,` these parts in an assembled position.

lt will be apparent that by the usel oit these columns which are constructed princi pally oit cast steel, triangular truss structures are formed at opposite ends of the side traine, the members of which comprise the outwardly converging ends 100 and 20G of the upper and lower arch bars which are secured to the tops ot the journal boxes l and the upright columns 16 connecting the separated parts of these arch bars. lli/laniestly this structure prevents the lower arch bar from dropping under the load strains and theupper arch bar trombe-ing raised by any tendencyr to draw the journal boxes toward each other, therebi,T obtaining the greatest benefit of cast steel construction where saine is most needed and increasing the safety oit the arch bars.

Furthermore, by the use ot columns han ing pillars ot yolre torni embracing the longitudinal bars of the side trame the constant teetering or vibration of these bars relatively to the columns cannot` result in' any loosening or breaking or' the connection between these bars and the columns as treoLIuentlifV occurs in columns which depend on vertical tio bolts tor their connection Awith the longitudinal luirs inasmuch as such bolts tend to loosen slightl)7 under load which permits the arch bars to bend continua-lhY while being loaded and unloaded until they finally brealr` Aside trom the greater seciiu'ity and durability obtained by this construction the. parts can be produced at coin]iaratiroly low cost and can also be readily and easily assembled as well. as dismembered tor inspection, adjustment or repairs.

"When the side traine is ot considerable length it preterable to connect the pillar ot each inner column 15 with the pillar ot each companion outer column 16 by means ot a truss or brace 4S which. as shown in 17 E? an d 3, mai7 extend jl'from the upper end ott each inner pillar to the lower en d ot each outer pillar and be 'formed intcoralliY therewith, thcrebi7 producing' an exec dingly strong structure which capabh-ifoi sustaiuing `the greatest loads liable to be imposed upon the saine without making the side traine unduly heawjv and without materialiilY increasing the cost ot the same. l'n the caso of a side iframe haring a wheel base ot inoderatc length this truss or brace may be omitted and thereby effect a corresponding saring in weight and cost.

For convenience in supporting the brake beams each ot the pillars ot the outer columns 16 is provided on the inner side ot' its upper part with a laterally proiectiua` arm t9 to which may be pivotall7 secured by means of a horizontal transverse pin 50 the hanger 51 which carries at its lower end, the beam ot the adjacent brake shoes, shown in Fi 1,v 2 and -l. The arch bars are preterahljyY so constructed that atter he same hare been. assembled with thro colui'nns the corresponding ends 100: Q00, thereof are separated slightly, as 'indicated by dotted lines in 1.I but these are drawn tightli tcgctlier upon securing the saine to the jourH nal boxes, as shown by t'ull lines in the saine ldd ligure. By thus constructing the ends of the arch bars they have to be sprung into final assembled position, the assembling of same is facilitated and the tension of the 4keys or fastening devices of the adjacent 'columns is increased, thereby producing a more rigid construction.

lVhen the wheel base of the car truck is comparatively short the outer columns may be omitted and the connection between the upper and lower arch bars and the tie bar may be effected solely by a pair of inner columns, as shown in Figs. 6-10, these columns being constructed as follows In the constructionshown in Figs. 6 to l0, each of the columns comprises an upright pillar 53 preferably constructed of cast steel and provided at its upper end with an opening 1S which receives the upper arch bar l and a lower downwardly opening recess 80 which receives the lower arch bar and tie bar. The upper arch bar rests with its un-V derside against the lower side of the upper opening 18 and is interlocked therewith so as to prevent the upper arch bar and the respective inner pillar from moving horizontally lengthwisevof the frame one relatively to the other, this being preferably effected bv means of a locking pin 2O formed integrally with the pillar and proj ecting upwardly from the bottom of its upper opening and engaging with an opening` 2l formed in the adjacent part of the upper arch bar. These parts are held in an interlocked position by means of a locking block or fastening member 22 which is interposed between the upper side of the arch bar and the tcp of the upper opening in the pillar. ln its preferred form the upper side of the locking block is constructed in the form of a wedge having its upper side 23 inclined lengthwise and engaging with a correspondingly inclined face 24- at the top of the upper opening in the pillar, as shown in Fig. 10, so that upon drawing this locking block lengthwise between the top of the pillar and the top of the upper arch bar until these inclined surfaces engage tightly with each other, the upper arch bar will be pressed firmly down on the bottom of the upper opening in the pillar and securely hold these parts in position relatively to each other. This tightening of the wedge-shaped locking block as well as the holdingof the same in position after'the parts are assembled may be effected in various ways but preferably by means of a horizontal clamping bolt 25 arranged length-- wise with its shank in opposing longitudi nal.' grooves 2G, 27 formed in the top of the upper pillar opening 18 and the upper side of the upper locking block and bearing with its head 28 against one end of the locking block and the adjacent side of the pillar while its nut 29 bears against the other end of the locking block and the adjacent side of the pillar, as shown in Figs. 6, 8, 9 and l0. ldlashers 30 are preferably interposed between the head and nut of the clamping bolt 25 and the opposing surfaces of the locking block and pillar.

In the construction shown in Figsf to 9 the lower arch bar and the tie bar are conneeted with the pillars 53 by the same means which are shown in Figs. l and 5 for connecting the lower arch bar and the tie bar with the inner pillars l5 and the same reference characters and description Vtherefore apply to the corresponding parts in these gures. v

rIhe lower parts of the pillars of the colf umns 53 are preferably provided with transverse ears 4:3 to which the flanges 10 of the spring plank may be secured byrivets 44 or otherwise. At each end of the bolster 13 the same is provided on its opposite vertical sides with pairs of guide lugs 45 which form a guideway and which receive between them the adjacent upper opposing salient guide portions 46 of the inner pillars 53, whereby the bolster is guided in its vertical movements on these pillars. l/Vhen the bol-Y ster is made of cast steel these guide lugs are preferably formed integrally with the bolster, as shown in F igs. l, 3, 6- and 7 but in some of the other types of holsters these guide lugs are made separate therefrom in the form of blocks and secured thereto in any suitable manner. For the purpose. of permitting the bolster t0 be removed from the side frame without dismembering the latter the inner lower opposing parts 'of the inner pillars 53 are provided with're-A casses 4-7, as shown in Fig. 6, which recesses are of sufficient depth so that upon removing the springs 11 and then loweringthe bolster until its guide lugs l5 are arranged in line with these recesses, it is possible `to pass the guide lugs of the bolster laterally through the recesses 47`of the inner pillars for the purpose of assembling or dismembering the side frame and bolster.

In this construction of side frame which employs but a single pair of columns the brake hangers 54C are pivotally mounted on arms 55 projecting laterally from the inner upper parts of the pillars 53 of these columns similar to the manner with reference to the outer or end columns shown in Figs. l, 2 and l.

In the construction shown in Figs. 11 and 12, the upper arch bar bears against the upper end of a vertical slot 56 formed in the pillar 57 and the opening 21 inthe arch bar is engaged by a locking pin 58 formed on the upper side of a loc-king wear block 59. whichv is secured to; the central part of the pillar within its vertical slot 5,6,- in such a marmer that lthis block may be moved vertically therein to permit of assembling or dismembering the parts of side frame or bolster. The pin 58 also engages with a socket 580 in the upper part of the pillar 57 while that side of its lower end opposite the bolster 13 engages with an abutment 581 formed by a transverse brace on the central part of this pillar. After the locking block 59 has been properly assembled with the upper arch bar and the pillar 57 the same may be held in place by various means, for instance, by means of a horizontal fastening pin or rod 60 passing transversely through corresponding openings in the central part of the pillar 57 and the upright locking block 59 and provided with a shoulder 61 bearing against one of the outer walls of the respective pillar and a screw nut 62 bearing against the opposite outer wall of this pillar, as shown in Figs. 11 and 12. This pin may also be provided with an inward extension 63 upon which the upper end of the adjacent brake hanger 64E may be mounted and retained thereon by means of a Cotter pin G5 so that this fastening pin serves the double purpose of securing the locking block in place and also supporting the brakes, whereby a separate support for the brake shoes is rendered unnecessary in substantially the same manner as in the construction shown in Figs. 1 to 9. ln the construction shown in Figs. 11 and 12, the bolster is guided by means of guide lugs 66 on its opposite vertical sides engaging with the inner opposing vertical guide portions 67 on the vertical locking blocks 59. `When it is desired to remove the bolster in this construction this may be accomplished in the same manner as has been already described with reference to the construction shown in Figs. 1 to 5, or this may be effected by first taking out the springs 11 and then dropping the bolster until its guide. lugs 66 are below the vertical locking blocks 59 after which the bolster is free to be moved sidewise from the side frame through the recesses 68 in the lower parts of the pillars 57. The parts may also be assembled in the same manner. The lower arch bar and the tie bar are secured to the lower ends of the pillars 57 in the same manner as that shown regarding the columns 15 in Figs. 1, 5, 6, 8 and 9 and the same description and reference characters apply to the corresponding parts in the construction shown in ligs. 11 and 12.

ln the modification of my invention shown in Figs. 13 and 14; the pillar 40 of the column is provided in its upper part with an upper opening 70 the upper side of which is engaged by the top of the upper arch bar and the latter is interlocked with this pillar by means of a vertical locking pin 71 depending from the top of this opening through the opening in the upper arch bar, and these'parts are held in this position by means of a locking wear block 72 arranged in the upper opening of the pillar 40 and bearing with its upper end against the underside of the top arch bar and with its lower end against the bottom of said upper opening in the pillar. The locking block 72 is retained in proper position on its pillar by means of a horizontal fastening pin 73 passing transversely through corresponding openings in these parts which pin also extends inwardly through openings formed in an arm 74 projecting laterally inward from the upper part of this pillar and serves as a support. for the hanger 75 of the adjacent brake beam. The locking block 72 is further interloclred with the pillar 10 by providing its upper end with a notch or recess 76 which receives the lower end of the pin 71 of this pillar, and the lower part of the locking block is provided with a horizontally projecting supporting lug` 77 which enters an auxiliary opening 7 8 formed horizontally in the central part of the pillar 40. In the construction shown in Figs. 13 and 14 the bolster is also guided on the inner part of each locking block 72 by engaging opposite sides of the latter by guide lugs 79 on the bolster. In the construction shown in Figs. 13 and 14 the lower arch bar and tie bar are arranged in a recess or notch 80 which `is formed in the lower part of the pillar 40 and opens downwardly from the lower end thereof and the lower arch bar and tie bar are interlocked with this pillar by means of a locking pin 81 depending from the upper side of this recess and engaging with the corresponding openings formed in the lower arch bar and tie bar. The latter are confined in this recess and held firmly in engagement with the upper side thereof and in engagement with the pin 81 by means of a horizontal lrey 82 engaging with the underside of the tie bar and passing transversely through corresponding openings in the lower members of the bifurcated part of the pillar 40; this key being held in place by engaging the head 83 at one of its ends with one of the outer walls of this pillar and providing its opposite end with a cotter nin` 84 which engages the opposite outer wall of the same. This construction has the advantage of convenience for frequent inspection of the same and permitting of readily determining whether or not the side frame is in the proper condition, as well as permit ting of readily assembling the parts and dismembering the same for repairs, if necessary.

In the construction shown in Figs. 15 and 16 the lower arch bar and tie bar are con nected with the pillar 85 of the column in substantially the same manner as that shown in Figs. 13 and 141-. The up er arch bar, however, in the construction siiJown in Figs. 15 and 16 is secured to this pillar by providing the upper end of the latter with a pnlmmm connecting' the Upper and lOWel: said columns being independent of said har".
